A field experiment was carried out at El-Mahmoudia command area at
El-Beheira governorate, Egypt. during two growing seasons summer and
winter 2014/2015, to Improve irrigation water conveyance efficiency
using lined canal and upvc buried pipes under Egyptian conditions. The
experiment consists of three types of on-yield water distribution canals
(Merwas); Earthen canal, Lined canal and Upvc buried pipes. Six
Evaluation parameters were measured: conveyance efficiency, water
saving, irrigation time, land saving, cropping intensity and crop yield, the
financial analysis had been applied The result showed that the
conveyance efficiencies were 65%, 92.2% and 98. 7% in winter, while the
conveyance efficiencies were 59.6%, 87.1% and 98.7% in summer, for
earthen canal, lined canal and buried pipes. respectively. The impact of
development on reducing conveyance losses comparing with earthen
canal were 68.1 % and 96.3 for summer, while it was 77.7% and 96.3 for
winter, under lined canal and upvc buried pipes, respectively. The impact
of improvement on decreasing irrigation time was ranged from 50% to
60% for the different field crops..The benefits of land saving were about
0.8% of the total saved area after development by lined canal and 1.4% of the total command area saved after development by upvc buried pipes. it had become available for agriculture. The highest profit as a percent was obtained under maize, for both lined canal and buried pipes, respectively.
